Alucard was first able to sit on chairs in Symphony of the Night. The one time in the game where sitting in a chair has a gameplay effect is in the confession booth in the Royal Chapel. Sitting in a chair on one side will summon a ghost priest to appear on the other side. If the priest does not attack Alucard, he may drop a Grape Juice (or Wine in the original Japanese versions). Sitting on the other side will summon a ghost lady who may attack Alucard or confess him her sins.
Olrox has a banquet table set up in his quarters. While sitting at one table, he offers Alucard to take a seat at the other side of the table, which he can do before the battle commences.
The Sega Saturn version of the game features a Song Lyrics Card. When equipped with a Fairy Familiar, sitting on a chair for a while will cause the familiar will perch on Alucard's shoulder and start singing a tune.
The concept of sitting in a chair is greatly expanded in Castlevania: Curse of Darkness and is a major, if still mostly useless, component of the game. Chairs of different types can be found hidden throughout the game. Sitting in each chair may cause a different effect. The Save Room itself is a room with a chair, which is the most common chair in the game. There are also Teleporter Seats that allow transportation through the maps, and gunneries which also have their own seats.
Each map has a hidden chair that serves purely as amusement. In addition, there is a Chair Room in Cordova Town which contains a copy of each chair that Hector has sat upon during the course of the game, making this a hidden mini-game where the player can "collect" the chairs by sitting on them.
After finding (and sitting) on all possible chairs in the game, the final chair, which contains a huge "Complete!!" sign, appears in the middle of the Chair Room as a trophy.
